Canada’s largest city has instituted a two-tiered suite of voluntary and mandatory programs to enforce sustainability standards in all new developments.
Toronto Green Standard (TGS) is a two-tier package of environmental performance measures designed to address Toronto’s five major environmental challenges: air quality, climate change, water quality and efficiency, urban ecology, and solid waste. TGS ensures that all new developments in the city achieve high energy performance targets. Tier 1 compliance is required for all new construction in Toronto, while Tier 2 is a higher, voluntary level of performance, and compliant projects may be eligible for a partial refund of development expenses.
115,000 tons of CO2 reduced through TGS each year

TGS includes a number of initiatives that address the city’s five key environmental challenges. For instance, to promote water use efficiency, Tier 1 requires buildings to retain at least the first five mm from each rainfall event, while Tier 2 requires the retention of at least 25 mm. Tier 1 requirements have been applied to more than 850 new construction projects, including 75 high-rise buildings, since the program launched, and 15% of new buildings are targeted for Tier 2 level compliance. This program has made Toronto a regional leader in energy efficiency measures. Currently, three municipalities outside of the City of Toronto have adopted the performance measures in their jurisdictions, and other municipalities are looking to do the same.
The challenge
Toronto has experienced unprecedented levels of new development in recent years. But positive economic growth can often result in detrimental environmental consequences. TGS ensures that sustainable building standards are part of the city’s growth and development, making Toronto a regional leader in sustainability.
Co-benefits
Economic A 2008 cost-benefit study indicated that implementing Tier 1 would result in savings of more than $1.2 billion in avoided hard infrastructure expansion costs to the city over the next 25 years.
Environmental Over 2 million liters of water have been saved each day from high-efficiency fixtures required by TGS Tier 2, a potable water use reduction of 30%.
Social In order to promote cycling and a more pleasant urban environment, TGS requires the construction of nearly 200,000 new secure bicycle parking spaces.
